Let's go in order, so Manny v Hearns, Crawford v Floyd and so on. Then the winner of the Manny Hearns v winner of Crawford Floyd.
Depending on the bracket I think the finals would be between Hearns and whoever else. I don't think anyone else is beating Hearns in his quarter finals, semi finals etc...........so it would definitely be Hearns vs. "fill in the blank". Hearns would win though
Hearns imo but I think Whittaker would also have a good shot. Prime Floyd would have been a hard fight for anyone as well.
Hearns was so talented. He would be too much for all those fighters listed. Whittaker could be a dark horse though. Would have loved to have seen him rematch Leonard and Hagler still.
Hearns wouldn't win this tournament. He'd get stopped in some fight that he entered as a favorite, or possibly upset on the cards by Floyd. Edit: If the tournament allows him to start with Manny and skip Crawford and Tito, his chance is a little more favorable.
I've got Hearns winning it but I would say the guy with the best shot at beating the Hit Man would be Tito Trinidad. Tommy's weakness was his chin and Trinidad had great power., Not sure if I think Trinidad could win the whole thing but he would be the guy to beat Tommy if anyone was going to.
